SCCM 2012 R2 - Offline servicing error
I attended a customer site in which their Windows 8 image was failing to OfflineService through ConfigMgr 2012 with the error 'Failed to install update with error code -2146498513' and 'ErrorCode = 2095'

Offline Servicing is the act of installing Windows updates. Conventionally servicing is done in an online state refering

that the operating system is up and running when a change is made. Online servicing is done via Windows Update. Offline

means that the installation is happening against a non-running version of Windows. ConfigMgr mounts the WIM file with DISM

and then install updates against the mounted directory. This distrinction is important as certain updates cannot be installed offline i.e Service Packs. Teh registry key ..Component Based Servicing hold information pertaining to pending updates. When the key 'SessionsPending' has the value 3 ConfigMgr cannot continue with OfflineServicing and updates will read 'APPLICABLE' but error with 'error code -2146498513'

To resolve it would be advisable to recreate a custom Windows Image file and run Updates Online (rebooting). If you are unable to recreate your Windows Image follow these commands below modifying the Registry of the Wim Offline.

Find the registry key
HKLM\MyKey\Microsoft\Windows\CurrentVersion\Compnent Based Servicing\SessionsPending
Take ownership of root Key
Assign Full Control to Administrator
Edit the DWORD Exclusives to value 0 (in my case it was 3)

Unload the registry
reg unload HKLM\MyKey

Commit the changes to the wim
C:\>dism /unmount-wim /mountdir:c:\temp\mount /commit
